BACKGROUND OF THE INVENTION Field of the Invention

The present disclosure relates generally to a blender. Moreparticularly, the present disclosure relates to a blender which isprovided with a support member which supports the upper surface of amain body casing.

Description of the Related Art

Generally, a blender is referred to as a mixer or crusher, and is mainlyused for crushing or chopping food contained in a container body byrotating blades by the rotation of a motor.

In a normal blender, a main body having a motor operated by electricityis located at the lower side of the blender, and the container bodyreceiving food is seated on the upper side of such a main body. Bladescrushing or chopping food are provided inside the container body, andare rotated by the rotational force of the motor.

Accordingly, when a user drives the motor by using a manipulation buttonor a knob of the main body after putting food in the container body, theblades receiving the rotational force generated by the motor crush orchop food contained inside the container body.

Various types of blenders have recently been developed in accordancewith a user's desire to facilitate the food intake of office workers dueto their busy daily life. That is, a small hand blender has beendeveloped, and a slightly larger blender has been developed that allowsfood to be crushed in a large capacity or at high speed.

Furthermore, a vacuum blender which cuts or crushes food by vacuumizingthe inside of the container body is also disclosed such that a foodmaterial received in the container body of the blender can be processedin a fresher state.

However, each of various types of blenders is provided with electronicparts such as a motor assembly and a PCB module for controlling theoperation of the blender, and during the operation of the blender, heatis generated in the motor assembly or the PCB module, and malfunctionthereof occurs.

In addition, as for a manipulation part composed of a touch button, aPCB provided under the manipulation part is moved, and thus themanipulation sensitivity of the manipulation part is decreased, andmanipulation thereof is not accurately performed. That is, in cookingequipment disclosed in Korean Patent No. 10-2057487 or Korean Patent No.10-198705, a manipulation panel provided under a display part which ismanipulated by a user or displays is not securely held, and thus themanipulation of the display part by a user is not accurately transmittedto the manipulation panel or a manipulation error thereof occurs.Additionally, due to the sagging of an outer casing, malfunction of theblender may occur.

Accordingly, the malfunction ofthe blender may be completely prevented.

Hereinafter, the operation of the blender of the present disclosurehaving the above configuration will be described with reference to theaccompanying drawings.

When the container body 100 is seated on the main body 500, the blenderis in a state of FIG. 1 , and in this state, the use of the blender ofthe present disclosure starts.

First, in order for a user to use the blender, power supply from theoutside may be required, and this power supply may be wirelesslyperformed by the wireless power module 520. That is, power supply fromthe outside may be performed in a method of using an inducedelectromotive force, and of course, power supply may be performed bywire.

The power of the wireless power module 520 may be supplied to partswhich require power, such as the motor assembly 600, the touchmanipulation part 504, and the power transmission means 700, and a usermay manipulate the starting or stopping of the blender by manipulatingthe touch manipulation part 504 or the knob 502.

For example, when a user is intended to start crushing food bymanipulating the touch manipulation part 504 or the knob 502, the motorassembly 600 may be required to be operated to rotate the blades of theblade assembly 200.

However, in this case, the detection system may determine whether thecontainer lid 400 is closed, and when the container lid 400 is opened,the motor assembly 600 and the blade assembly 200 may not operate.

Specifically, since the reed switch 234 is normally turned off, thepower reception means 220, the reed switch 234, and the lighttransmission module 810 may not form a closed circuit in the containerbody 100, and thus the light reception means 820 may not receive light.

Accordingly, when the light reception means 820 does not receive light,due to such a signal, the supply of power to the motor assembly 600 maybe blocked.

In this state, when the container lid 400 is closed, the permanentmagnet 232 of the container lid 400 may approach the reed switch 234,and thus the reed switch 234 may be turned on. Accordingly, the powerreception means 220, the reed switch 234, and the light transmissionmodule 810 may formed a closed circuit, so the light reception means 820may receive light generated by the light transmission module 810.

In this case, the closing of the container lid 400 may be detected, andaccording to the manipulation of a user, the operation of the motorassembly 600 may start and food inside the container body 100 may becrushed. Of course, in this case, the mounting of the container body 100to the main body 500 may be detected by the container body detectionswitch 960, and the operation of the motor assembly 600 may start.

In addition, in this case, the operation state of the blender of thepresent disclosure may be displayed through the display part 506 to theoutside, and thus a user may visually recognize the operation state ortime of the blender.

Meanwhile, when a user opens or closes the container lid 400 of thecontainer body 100, the user may open or close the container lid 400 bygripping the upper half part of the cap 450 with the hand. The containerlid 400 may be in close contact with and held on the upper surface ofthe container body 100 by a user pushing the container lid 400 downwardfrom a side above the container lid 400. In this case, a gap between thecontainer lid 400 and the container body 100 may be covered by thegasket 402 provided on the outer surface of the container lid 400.

Furthermore, the cap 450 mounted to the center portion of the containerlid 400 may be removed therefrom by a user, and this is possible when auser grips the upper end of the cap 450 and rotates the cap 450 asdescribed above.

When the cap 450 is removed from the container lid 400, a user mayinsert food into the container body 100 through the lid hole 401, andmay control food inside the container body 100 with a rod passingthrough the lid hole 401.

Due to the operations of the motor assembly 600 and the blade assembly200, food contained inside the container body 100 may be crushed ormixed and the work intended by a user may be completed. In this case, auser may move the container body 100 upward from the main body 500 to beremoved therefrom, and then may open the container lid 400 to take outfood contained inside the container body 100.

In addition, according to the operation of the motor assembly 600, thecooling fan 610 connected to the lower end of the motor shaft 622 mayrotate.

When the cooling fan 610 rotates, external air may be introduced intothe main body 500 and then may be discharged back to a side under themain body 500.

Specifically, according to the rotation of the cooling fan 610, externalair of the side under the main body 500 may be introduced upward alongthe air introduction hole 514 formed in a position adjacent to the rightend of the base end 510.

The external air introduced along the air introduction hole 514 may flowupward along the air introduction guide hole 588 of the base plate 540and may pass through and exchange heat with the PCB module (the inverterPCB module 562) and the heat dissipation member 544 provided above thebase plate 540. That is, the PCB module (the inverter PCB module 562)and the heat dissipation member 544 may exchange heat with external airto be cooled.

Next, the external air may be collected in the center of the inner upperside of the main body 500, and may be introduced through the housingholes 638 formed in the upper surface of the motor housing 630 into themotor assembly 600.

The air introduced into the motor assembly 600 may exchange heat withthe coil of the inside of the motor 620 so as to cool the motor 620, andcontinuously may be discharged to the lower side of the motor assembly600 and may be introduced into the air guide 550.

Air discharged laterally from the inside of the air guide 550 by thecooling fan 610 may flow to the left of the air guide 550, and may passthrough the air discharge guide hole 586 formed in a position adjacentto the left end of the base plate 540 to flow downward, andcontinuously, may pass through the air discharge hole 512 formed in aposition adjacent to the left end of the base end 510 to be dischargedto a side under the main body 500.

Through such a process, air introduced into the main body 500 may bedischarged back to the outside of the main body 500, and in thisprocess, electronic parts provided inside the main body 500 may becooled.
